Driver&#39;s license detector

ABSTRACT

A license detector system enables a person such as a police officer to monitor vehicles on the road to ensure drivers have valid licenses. Within each valid license is an RFID tag which contains specific information and each RFID tag is able to send that information to a detector when requested. To use the system, the police officer aims the detector at a vehicle, initiates the signal to be received by the RFID tag within the license and waits to receive a signal back from the RFID tag. If a signal is received, then a valid license has been detected within the vehicle. However, if no signal or an invalid signal is received by the detector, then no one, specifically the driver of the car, has a valid license. Upon discovering such information, the police officer should be justified in stopping the vehicle and taking the necessary police action.

FIELD OF THE INVENTION

The present invention relates to the field of radio frequencyidentification. More specifically, the present invention relates to thefield of utilizing radio frequency identification within a driver'slicense or other identification device.

BACKGROUND OF THE INVENTION

Radio Frequency IDentification (RFID) is utilized in many applicationsincluding smart cards, transport payments, product tracking andpersonnel tracking. In each of these applications, an RFID tag ortransponder is attached to or incorporated within a product or person.Then, the RFID tag is used to identify the product or person using radiowaves.

There are many different types of RFID tags. The three main typesinclude passive, semi-passive and active tags. Passive tags require nopower source whereas semi-passive tags use a small power source andactive tags need an internal power source.

Passive RFID tags are capable of functioning without an internal powersource. A tiny amount of energy is needed for the integrated circuitwithin the tag to function, and the electrical current induced in theantenna by the incoming radio frequency signal provides enough power. Itis common for passive tags to use the antenna to collect power from theincoming signal and also to transmit the outbound signal. Furthermore,since passive tags have no internal power source, they are able to beproduced extremely small. Passive tags also generally have a very longlife span since there is no internal power source to drain or fail.

Semi-passive RFID tags utilize a small battery which powers the RFID tagthus removing the need for specialized two-way antennas which are usedin passive RFID tags.

Active RFID tags require an internal power source which is used to powerthe integrated circuit to generate an outgoing signal. Active tags areconsidered to be more reliable than passive tags with their ability totransmit at higher power levels. Active tags are also able to be maderelatively small, such as the size of a coin. As technology improves,active tags will eventually become even smaller.

As mentioned above, RFID has many applications. Another applicationincludes being used within a driver's license. There has beensignificant discussion of utilizing RFID within drivers' licenses forthe purposes of identifying drivers without having to manually inspectthe license. Licenses would not have to be put into a reader device likethey are today where a magnetic strip is used to store information.Rather, the license could be scanned using an RFID scanner. “Wired News:RFID Driver's Licenses Debated”http://www.wired.com/news/privacy/0,1848,65243,00.html?tw=wn_tophead_5Although utilizing RFID within driver's licenses is known, the concepthas only been implemented to remove the need for swiping the driver'slicense.

Furthermore, due to the fourth amendment of the Constitution whichprohibits unauthorized searches and seizures, police officers are unableto pull over drivers for simply suspecting they are driving without alicense. The police must first have a reason to pull over someone, suchas a traffic violation. This presents a problem because there are manyindividuals who drive illegally without a valid license after it hasbeen suspended, revoked or has never been received for one reason oranother. Yet the police are generally unable to do much to stop suchoccurrences since their opportunities to cite these violators arelimited. The unlicensed drivers are potentially hazardous and would beticketed under state law for driving without a license if discovered.Hence, an implementation that does not violate the fourth amendment yetis able to detect drivers without a valid license is highly desirable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A license detector system is described herein. The license detectorsystem includes a detector and a Radio Frequency IDentification (RFID)tag where the tag is embedded within a license. The detector has theability to detect the existence of an RFID tag from many feet away (e.g.more than 10 feet away) while the tag is moving at high speeds (e.g.while in a vehicle).

FIG. 1 illustrates a block diagram of the present invention. An RFIDdetector 100 includes a processor 102, a transmitter 104, a sensor 106,a verifying component 108 and an indicator 110 all coupled together by asystem bus 112. As apparent to those skilled in the art, the transmitter104 and the sensor 106 could also be integrated into a transceiver. Alicense 150 or identification card or device includes an RFID tag device152 which is able to communicate with the detector 100. The license 150which contains the tag device 152 is preferably a standard driver'slicense. Alternatively, the license 150 is any other appropriateidentification, membership or license card or device. The communicationbetween the detector 100 and the tag device 152 occurs by the detector100 sending a first signal 140 to the tag device 152 and then the tagdevice 152 sending a second signal 142 back to the detector 100. Thesecond signal 142 contains information about the tag device 152. In someembodiments, the information includes all of the information on thelicense 150. Other implementations include less information.

Within the detector, the processor 102 performs standard processingfunctions in addition to processing the information received from thetag device 152. The transmitter 104 sends the first signal 140 to thetag device 152 to initiate data transfer. The sensor 106 then receivesthe second signal 142 returning from the tag device 152. In someembodiments, the verifying component 108 is used to verify theauthenticity and validity of the second signal 142 to prevent cloning orother attempts to improperly trick the detector 100 into believing avalid license with a tag device is present. The indicator 110 isimplemented to indicate the status of the tag device 152. Furthermore,the indicator 110 is implemented in a variety of ways including but notlimited to, one or more visual confirmations, one or more light emittingdiodes (LEDs) or a liquid crystal display (LCD).

For example, in some embodiments, two LEDs are utilized where the firstLED is red and the second LED is green. After the detector 100 sends outthe first signal 140 from the transmitter 104, if the second signal 142is received at the sensor 106 within a designated time period, the greedLED is illuminated to indicate that a valid tag device was detected.However, if the second signal 142 is not received in time, then the redLED is illuminated to indicate that no valid tag device was detected.Furthermore, additional LEDs are able to be implemented if desired, suchas one to indicate the second signal 142 was received, but it was notverified by the verifying component 108.

In other embodiments, an LCD display is able to present information intext form. Using an LCD as the indicator 110 is also able to presenteven more information including the entire set of information shown on adriver's license including name, address, birth date, height, weight,sex, and eye color. For applications where this information will notgenerate privacy issues, such information is able to be retrieved.However, when privacy is a likely concern, the use of a set of LEDsshould be able to stifle such worries since a red LED versus a green LEDprovides no personal information other than whether the person has avalid driver's license or not. Thus, in some embodiments, all of theinformation on the front of a driver's license is sent from the tagdevice 152 to the detector 100. However, in other embodiments, only astatus signal is sent without providing any personal information.Therefore as much or as little information is able to be retrieved fromthe tag device 152 as desired. The tag device 152 simply needs to beconfigured accordingly.

FIG. 2A illustrates an embodiment of the present invention. The detector100 is within a hand-held or portable unit shaped similar to a radargun. Other shape implementations are possible. As a vehicle 200approaches the person or police officer with the detector 100, thepolice officer aims the detector 100 at the vehicle 200 and transmits afirst signal 140 directed at the vehicle 200. Since the passenger inthis example has a license 150 with a valid tag device 152, a secondsignal 142 is sent back to the detector 100. The police officer is thenable to view the indicator 110 (FIG. 1) and determine that this vehicledoes in fact contain a valid driver's license.

In some embodiments, the processor also communicates with a remotesystem 230 to determine the status of the license 150 such as in goodstanding, suspended or revoked. A request signal 144 is sent from thedetector 100 to the remote system 230 requesting the status of thespecific license 150. The remote system 230 then sends the requestedstatus back in a status signal 232 to the detector 100.

In some embodiments, the tag device 152 within the license 150 isutilized for purposes other than determining if a valid driver's licenseis within a vehicle. For example, instead of requiring people topurchase transponders to communicate with automated toll boothcollectors such as Fastrak, a user's license with tag device is able totransmit the necessary information.

FIG. 2B illustrates an embodiment of the present invention. A detector100′ is positioned on a stationary object such as a light post ortelephone pole. In the example shown, a first signal 140 is transmittedtowards an approaching vehicle 202. The driver of the vehicle 202 doesnot have a valid driver's license with tag device and thus a secondsignal is not sent back to be received by the detector 100′. Thedetector 100′ is similar to the detector 100 with additional components.As soon as it is determined that the vehicle 202 is being driven withouta licensed driver, a second transmitter 120 transmits a third signal 146containing this information to the authorities, likely remote from thelocation of the detector 100′. The information reaches the police viaany possible means including satellite, cellular towers or the like. Insome embodiments, the information transmitted is limited to the factthat a car passed by without a valid license inside to be used for datacollection to determine how many unlicensed drivers are on the road.With additional information transmitted, such as a picture of thevehicle or the vehicle's license plate, from a camera 220, the policeare able to then take that information and use it to pull over thevehicle 202 soon thereafter. Although the camera is shown separate fromthe detector 100′, in some embodiments the camera 220 is included withinthe detector 100′. Since the stationary object is able to be implementedwithout human intervention, an additional sensor 122 is utilized todetect when vehicles are in the correct position to transmit the firstsignal 140 to detect a license.

In some embodiments, the detector 100′ is positioned within a toll boothwherein the vehicle does not receive access to pass through if a validlicense is not detected.

In another embodiment, instead of the detector being hand-held, thedetector is secured within or on a police car, so that the policeofficer is able to drive and scan vehicles for valid driver's licenses.

FIG. 3 illustrates a flow chart of a process of utilizing the presentinvention. In the step 300, a first signal is transmitted from adetector to a tag device within a license. In some embodiments, thelicense is in a vehicle. In the step 302, the first signal is receivedat the tag device. Then, in the step 304, the tag device transmits asecond signal back to the detector. In some embodiments, the tagdevice's authenticity is verified, in the step 306. In the step 308, thestatus of the tag device is indicated on the detector. In someembodiments, the status is indicated using a set of LEDs, and in otherembodiments, an LCD is utilized to indicate the status. Moreover, insome embodiments, the status of the tag device is determined by sendinga signal to a remote device for to determine the status and then theremote device sends the status back to the detector.

FIG. 4 illustrates a flow chart of a process of utilizing the presentinvention to determine if a vehicle contains a valid driver's license.In the step 400, a police officer acquires a target vehicle and aims thedetector at the vehicle. In the step 402, the police officer, transmitsa first signal from the detector towards the target vehicle. The policeofficer then waits to receive a second signal from a tag device withinthe target vehicle, in the step 404. The time to wait is variable,although it should be set depending on how long the second signal takesto be received. If the second signal does return in the step 406, thenthe indicator within the detector indicates that the target vehicle doescontain a licensed driver, in the step 408. If the second signal doesnot return in the step 406, then the indicator within the detectorindicates that the target vehicle does not contain a licensed driver, inthe step 410. This process is able to be implemented with a hands-offsystem as well, such as the one described in FIG. 2B where the detectoris affixed to a light post, tool booth or other fixed object. In thehands-off system, an additional step of sending a third signal to aremote location is implemented. The information contained within thethird signal is able to inform the police if further action needs to betaken. In some embodiments, an additional signal is sent to a remotesystem to determine the status of the license where the remote systemthen sends the status back to the detector. Furthermore, the process isable to be repeated rapidly for each vehicle that passes by thedetector.

In the preferred embodiment, the tag device utilized within the licenseis passive allowing a very small form factor and thus requiring little,if any, change in the current design of the license. In otherembodiments, semi-passive or active tag devices are implemented. As thedesign of items such as batteries gets smaller, it will be possible toimplement even an active tag device within the license withoutsignificant modifications.

In some embodiments, in addition to detecting valid driver's licenses,the license detector system is able to detect fishing licenses, huntinglicenses, pilot's licenses, government issued identification and othertypes of licenses or membership cards. For example, if a department offish and wildlife ranger were able to simply drive around a lake andpoint and click to determine if fishermen have valid fishing licenses,the process would be much more efficient to detect violators of the law.Furthermore, with the increased efficiency, more areas of the lake areable to be investigated, and thus more fisherman will purchase fishinglicenses out of fear of being caught.

To utilize the present invention, a user, typically a police officer orsomeone with authority, directs the detector towards a target. Thetarget is a vehicle such as an automobile or a boat. The target couldpotentially be an individual as well. After aiming at the target, thepolice officer activates the detector which sends a first signal towardsthe target. The first signal is received by a tag device embedded withina license if the license is within the target. After receiving thesignal, the tag device sends a second signal back to the detector. Afterthe detector receives the second signal, the signal's validity isverified, in some embodiments. In some embodiments, a remote system isutilized to determine the tag device's status. An indicator indicatesthe status of the tag device, so that the police officer is able todetermine whether further action is necessary. If a tag device was notdetected within the target, then the second signal would not be sent andafter a specified period of time, the detector would indicate that thetarget did not have a licensed driver. The police officer is then ableto use this information to pull over drivers who are driving withoutvalid driver's licenses or for fishing rangers to cite fishermen withoutvalid fishing licenses.

In operation, the present invention is used to detect the existence ofvalid licenses within a vehicle. Specifically, police officers are ableto implement the detector similar to a radar gun used for speed. Thepolice officer uses the detector to send a signal to a specified vehicleand then waits to see if a valid return signal is received. If thedriver has a valid driver's license containing an RFID tag, then a validsignal will be returned to the detector. If a valid signal is notreceived, the detector will inform the officer, and he will then have areason to pull over the driver and cite him/her for a driving violation.In some embodiments, the detector is not hand-held, but is positioned sothat it can detect valid driver's licenses and then transfer informationto the authorities such as the police.
